[转] Win7 文件共享报错存储空间不足，无法处理此命令

Win7共享，Win7访问正常，但XP偶尔碰到这个问题，有待继续观察。

总是遇到Win7 文件共享报错提示一般是“存储空间不足，无法处理此命令”

然后网络共享就打不开了要想重新打开需要重新启动 Server服务

虽然一直对windows的cifs共享的可靠性不抱什么希望不过频繁的断还是令人刚到郁闷

今天搜索了几篇文章照着修改了一下自己的系统好像有点效果正在观察中。。。

现象

客户端提示“存储空间不足，无法处理此命令”

服务器端日志

“服务器无法通过系统非页面共享区来进行分配，因为共享区当前是空的。”

“服务器无法通过系统非页面共享区来进行分配，因为服务器已达非页面共享分配的配置极限。”

修改2个位置

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

LargeSystemCache 修改为1

HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

Size修改为3

官方解释键值作用

LargeSystemCache

Determines whether the system maintains a standard size or a large size file system cache , and influences how often the system writes changed pages to disk.

0
Establishes a standard size file-system cache of approximately 8 MB. The system allows changed pages to remain in physical memory until the number of available pages drops to approximately 1,000. This setting is recommended for servers running applications that do their own memory caching, such as Microsoft SQL Server, and for applications that perform best with ample memory, such as Internet Information Services.

1
Establishes a large system cache working set that can expand to physical memory, minus 4 MB, if needed. The system allows changed pages to remain in physical memory until the number of available pages drops to approximately 250. This setting is recommended for most computers running Windows 2000 Server on large networks.

简单来说这个和文件系统缓存有关它涉及到FS CACHE和系统换页之间的平衡

对于数据库等应用由于cache由应用自行管理所以这个值建议不动

对于家用现在大家内存都很大了所以我个人认为大家都应该设置成1 这样提高性能

当然这个值我个人认为和网络共享好像没啥关系

第二个值的解释

Size entry (which is in the HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters subkey)

Option setting

Minimize memory used      1
Balance          2
Maximize data throughput for file sharing    3
Maximize data throughput for network applications 3

这个值可能是官方偷懒没写具体机制也可能是我没有找到总之只有建议配置方法

没有详细解释

另外大家还有建议修改一个值

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\IRPStackSize
